I'm doing a science experiment with my son. We have three 1.5V solar panels
wired in parallel in order to supply the 1.5V/400mA needed to power a small
DC fan. This works fine in sunlight or some other really bright light
source. He needs to do a demo in a classroom and my flashlight doesn't
supply enough photons to do the job. What's the best way to give the solar
panel enough help so that it still takes a flashlight to power the motor. A
(AAA) battery supplies too much current to connect it in parallel with the
panels. What's the best way to supply just enough current so that I'm still
under the motor threshold until I shine a flashlight on the panel? I don't
have an ammeter handy yet, so I can't tell you what sort of current the
panels are capable of supplying right now with the flashlight.
Thanks for your help
